Speccaton of Letters Patent.

Patented Oct. 20, 1908.

` Application led. January 13, 1908. Serial No. 410,519.

My invention relates toV heaters and has special reference to that class of heaters shown in United States Letters Patent granted to William H. Ramaley and Wil liam E. Lamerton on January 30, 1906, No. 811,335, in which cold air is taken into the heater to be heated for use in rooms or apartments. l

The object of my invention is to provide such a construction of heater which is cheap, simple and efficient in its construction and operation and will have a large area of heat radiating surfaces, as well as one whereby a large amount of cold air canbe taken into the same and be quickly and eiectually heated to the desired temperature.

A still further object of my invention is to provide such a heater in which the products of combustion are carried completely around the same in a circular path, so that the full benefit of the heating power thereof can be derived therefrom prior to the escape of said products from the heater.

My invention consists, generally stated, in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described, and par ticularly pointed out in the claim.

To enableothers skilled in the art to which my invention appertains, to construct and use my improved heater, I will describe the same more fully, referring to the accompanying drawing, in which Figure 1 is a side elevation of my improved heater, with the outer casing thereof shown in vertical section and with some of the parts broken away. Fig.` 2 is a vertical central section 4of the same taken on the line 2 2 Fig. 1 and looking in the direction of the arrow. Fig. 3 is a cross-section of the heater on the line 3 3 Fig. 1 looking in the direction of the arrow. Fig. i is a like View of the same on the line 4-4 Fig. 2 looking in the direction of the arrow.

Like symbols of reference herein indicate like parts in each of the figures of the drawing.

As illustrated in the drawing A represents my improved heater, formed of sheet metal, with the annular inclosing shell or casing l having the top 2 extending over the same.

which is provided with the inclined sides 3, and from which a plurality of fiues 4 lead for conveying the heated air from said heater to the different compartments to be heated. Adjacent to the bottom of the casing 1 is the cold air inlet` or duct 5 which leads into the said casing and opposite said duct and leading through said casing and into the burner casing for forming the combustion chamber, as hereinafter described, is the chute 6, which has a door 7 fitted to the outer end of the same and exterior of the casing 1 for access to the combustion chamber in the interior of said burner casing.

Mounted within the casing 1 is the burner casing 8 and a heating casing 9, the burner casing being annular in form and supported within the casing 1 by the legs 10 at its lower end, while its upper end is supported and braced within said casing 1 by the rods 11. The burner casing 8 is provided with a central chamber 12 extending through the same which is formed by the casing or cylinder 13 within said casing and forms with the said casing the circular or annular combustion chamber 14 around the same. Vithin the bottom of the chamber 111 is the perforated burner 15 for the burning of gaseous fuel within said chamber and to this burner are connected the feed pipes 16, which are provided with the usual air mixers 17 thereon and lead from the outside of the casing 1 where they are connected to the usual main supply pipe leading from any suitable source of supply. The burner 15 can be ignited from without the casing 1 through the medium of the door 7 and chute 6, and air is fed into the combustion chamber 14 and over said burner through a gauzed opening 7 in the door 7, which air is deflected into and along the lower part of the chute 6 by a plate 18 connected to sai-d door and set at an in- Y oline in said chute.

at an angle from the combustion vchamber 14` for being connected to the inner heating chamber 21 within said heating casing 9,k as hereinafter described.

The heating chamber is preferably annular in cross-section and is formed by the casing 9 which is composed of the outer wall 22 and inner wall 23 connected together by the top and bottom walls 24 and 25 for forming the circular heating chamber 26 between them and the cylindrical air chamber 27 withinl the wall 23. Within theichamber 26 is the horizontal 'partition wall 28 which is located centrally of the same vand is-pro vid-ed with a series ofvopenings 29 andan enlarged 'opening' or'passage-way 29 within the same whereby the contents ofthe upper heating compartment 30 formed in said chamber above said partition wall can pass into the lower compartment 31 on lthe opposite side of said partition, whiley said openings 29 can belof different size and of diffen ent numbers and arrangement in the parti# tion 28 according to the size of the furnace; A series -of iues 32 are arranged vertically through the compartments 30 and'31 and partition 28, suchl l-ues extending from the bottom wall' 25 tov the top wall 24'of the chamber'26 and being preferably staggered within the same.

The lower compartment 31 :of the chamber 26 is provided with anr escape or exhausti'lue'33 to carry the productsV of 'combustion outside of the heater A after the full benefit has been derived fromthe same, and `such VHue leads from the outer wall 22 of the casing 9 through the casing 1. Centrally supported within the air chamber 27 of the heating chamber is aI cylindrical casing 34 for forming the heating chamber 21, with which the combustion. chamber 14 comm-unicates by means of the tl'ues 20,' and such casing communicates with the uppenheating compartment 30 through a pipev 35. Afinestrip 36 having openings 36 therein is arranged vertically within the upperi heating compartment 30 and between the opening' 29 inthe partition 28 and the pipe 35 for directing the products of 'combustion around said compartment in one direction, which products can alsomeet with same passing throughthe'openinigs 36 in the strip 36, and

so they can pass down through the openings i 29 and 29 in the partition 28. A flue-strip 37 is arranged in a like plane with thestrip 36v in the lower compartment 31 for directing said products entering said compartment through .-the openings 29 and 29 to pass in an opposite direction around-said compartment and escape through the flue 33.

Extending through the casing 1 and burner casing 8 are the cold air iiues 38 which extend up within the combustion chamber 14 and to the top of the casing 8 forming4v said chamber and between the flues 20.

When my improved heater Ais inl operation, the prodiictsof Vcombustion, pass from thel combustion' chamber 14' upwardly through lthe fines 2O to the casing 34,y thence y through the pipe 35 into the upper compartment 30;,l thence they pass around the compartment 30= and downwardly into thel compartment 31 through the openings -29and passl around this casing or upwardly through the vchamber 12' ofthe cylinder 13, around the flues 20 and the heating chamber, as well as passing lupwardly throughthe flues 32 te the top 2 of the casing 1,' and then such air which hasbecome heated by contact with the heated surfaces of the; casings passes out through-the fines 4 to the rooms or apartments to'b'eheated. The other cold air entering the iiues 38passing through the casing 1- andcombustion chamber 14 will pass out of lthesameat the topI of the casing 8 and ming-le with the other air. from the inlet passing up around and within said casing Sand passup with the same to the flues'4 iin the manner 2 above described.

It will thus be seen that my improved i heater will provide for an .unusual 'quantity of cold'air to be taken intof the Asaine and heated therein for use, and such air will be thoroughly and: properly heated for the purpose intended, `while all parts of the heater structions can be used in' various other forms,

such: as stoves, furnaces, etc., while fuel other than gas can be used for operating the same.

Various modications and changes inthe design, construction and operation of my improved heater may be resorted to Without heating compartments therein, and vertical departing from the spirit of the invention or sacrificing any of its advantages.

What I claim as my invention, and desire to secure by Letters Patent, is

In a heater, the Combination of a casing having an air inlet and fines leading from said casing, a burner chamber and a heating chamber in said casing, fines between said Chambers, a partition having openings therein Within said heating chamber for forming straightvvay fines passing through said partition and compartments, and a fine-strip in each of said compartments and one of said 15 strips having openings therein.

In testimony whereof, I, the said IVILLIAM H. RAMALEY have hereunto set my hand.
